new and useful Powder-Sprayer, of which the following is a specification, The present invention appertains to powder Sprayers, and aims prilnar ilyto provide a simple, durable, compact and inex pensive contrivance for spraying dry "powders of divers varieties, especially insect powders, and which shall be convenient, serviceable and efiicient in its'use.

It is also the object of the present invention to provide a powder sprayer .which shall have means for regulating the amount of powder discharged or sprayed therefrom at each operation.

To the above and other ends, which will appear as the description proceeds, the in vention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spiritof the invention.

The preferred embodiment has been illustrated in the accompanying drawing, where- Figure l is a longitudinal central section of the sprayer, part of the cylinder being shown in full. Fig.2 is aphantoin fragmental perspective of the device. Fig. 3 is a sectional detail on an enlarged scale.

Referring specifically to the drawing, the sprayer embodies an air or force pump comprising the elongated cylinder or tube 4: having a suitable piston 5 working therein, the piston rod 6 passing slidably through the head 7 secured to the outer end of the cylinder and having a suitable handle 8 attached to its outer or free end. The details of'this force pump are of no moment and may be varied at will according to the whnn of the user.

A cylindrical powder receptacle or container 9 is attached to the inner endof'the cylinder 4, the said receptacle being. of a" "inits other end,or atthe corner diametrically opposite the corner to which the cylinder is attached, the opening 10 being elongated on a chordal line.

The cylinder 4 is provided wit-h an extension 11 passing diagonally through the receptacle 9 and terminating at its free end adjacent the opening 10, the extension pro- 1 jecting toward the said opening and the :free end thereof being flattened so as to provide an elongated opening 12 for the ext-ension complementing the elongated outlet opening '10.

A flattened nozzle 13 passes slidably through the elongated opening 10, the outer end of the nozzle being tapered and the inner end of the nozzle being slidable to and from the free end of the extension 11 so as to adjust the space between the extension and the nozzle.

Although the free end of the extension and the nozzle have been illustrated as be ing flattened, which is highly preferable, it is understood, that the contours of the said parts may be formed in any desirable manner.

The powderreceptacle 9 is also provided at one side with an opening or nipple 14: closed by the removable cap 15, in order that the cap may be removed for filling the receptacle with the powder to be sprayed.

I11 use, it being understood that the piston is arranged at the inner end of the pump, the outward movement of the piston Then, by forcing the piston inwardly, the

air ahead of the piston will be forced outwardly through the extension and across the gap to the nozzle 13. The air, which is laden with the powder or dust is thus discharged from, the nozzle, and the outward action of the air will also carry with it additional powder which trickles or gravitates over the free end of the extension 11. Each operation of the piston will therefore eject a certain'qua'ntity of powder in order to effectively spraysame, the flattened noz zle13 causing the emission of the air and which trickles or gravitates into the said gap.

The "present device provides a desirable and hand operative contrivance for spraying insect powders or the like for various purposes, theadvantages andcapabilities of the present device being evident from the foregoing, taken in connection with'the drawings, and it will be noted that the ob j'ects aimed at have been carried out satisfactorily. l Having thus described the invention, what is claimed is:

1. A powder sprayer embodying an air cylinder, a powder receptacle attached Uopies .of this patent may be obtained for It will be noted, that by adjusting.

thereto and having an outlet, a nozzle slidable through the outlet, a piston in the cylinder, and an extension for the cylinder. passing through the receptacle so as to project toward and terminate adjacent the in 30 ner end of the nozzle.

2. Apowder sprayer embodying an air cylinder, a cylindrical powder receptacle ot' lar er diameterattached to one corner thereto, and having anoutlet in the diago- 35 nally opposite corner, agplStQIiJn the cylin-.

der, and anextension for the cylinder passing diagonallythrough thereceptacle and terminating adjacent the outlet, and a nozzle adjust-able through the outlet. to and 4 0 from the free end of the extension. I

In testimony that we claim the foregoing as our own, we have hereto affixed our signatures in the presenceof two witnesses.
